[0002] Sewage treatment is the process of purifying sewage so that it meets the water quality requirements for discharge into a certain water body or reuse. Sewage includes many types such as domestic sewage, industrial sewage and agricultural sewage. Sewage contains solid waste such as domestic garbage, daily necessities, etc. Using a filtering device to filter the fixed waste to obtain a liquid without solid waste is an important process in sewage treatment. However, the structural design of the existing solid waste filtering device is very simple. The solid waste in the sewage is transported to the filtering device and the solid waste is only simply filtered. These solid wastes still contain a lot of sewage, which makes the filtering device bear too high a weight, easily causing overload and damage to the components responsible for transmitting the waste, and also easily causing sewage to be transferred to other areas.
